I can add that option, but as said, most modern streaming servers today support UTF-8 song titles, which support any language
An din UTF-8 that title would be displayed as Karel Gott - Když muž se ženou snídá...

I am not sure what you mean?! What scroll-menu are you talking about - if it is the list of predefined format examples, you find it, as these are only most commonly used examples. You can still type whatever valid song title format as you like into the box!
Please take a look to the appendix of the user menu or use the exact sample as provided above.
I am not sure what else should be missing...
